CAT12 with Brainstorm source analysis

Good day,

After I follow the instructions, I tried to display the .nii file and this is what is shown:

Is this what it is expected to be?
I am not sure that i will be able to perform any analysis on the data extracted from here.

The intention is to extract the source information obtained after the sLORETA analysis to compare it between several files and be able to identify the area that is shown in both.
Any ideas?

Thank you in advance!
